On August 3, 2026, the average daily gain in textile commodities was a modest 0.24%, but the internal divergence tells a more compelling story. Acrylonitrile jumped 2.69% in a single day, with a year-on-year surge of 44.42%, while polyester staple fiber fell 0.06%, the only decliner. This seesaw pattern highlights the deep-rooted tension between upstream cost-push and downstream demand absorption.
Upstream Surge, Cost Pressure Builds
Acrylonitrile rose from 11,133.33 to 11,433.33 yuan per ton, a year-on-year increase exceeding 40%, a rare move in recent chemical fiber markets. PTA followed with a 1.37% gain, up 25.01% year-on-year, both pointing to a systemic rise in petrochemical feedstock costs. For acrylic and polyester producers, this means procurement costs are being forcibly lifted, and the ability to pass through depends on end-order acceptance.
Notably, raw silk inched up only 0.07% and remains 9.39% lower year-on-year, the only negative on the list. This contrast indicates that cocoon supply fluctuations have not reversed weak silk demand; silk prices are more pressured by sluggish downstream satin consumption. Cotton, cotton yarn, and viscose staple fiber held flat but posted year-on-year gains of 14.20%, 5.11%, and 9.40% respectively, showing solid cost support yet lacking fresh catalysts.
Polyester Filament vs. Staple Fiber: Two Divergent Logics
Polyester filament series (POY, DTY, FDY) remained flat on the day but showed year-on-year gains between 17% and 24%, reflecting a significant recovery over the past year. Meanwhile, polyester staple fiber dipped 0.06%, with a milder annual rise of 14.96%. This divergence is not accidental: filament is tied to weaving and export order stability, while staple fiber serves filling and nonwovens, more sensitive to domestic consumption recovery. Spandex held at 29,666.67 yuan per ton, up 22.34% year-on-year, indicating resilient demand for stretch fabrics but limited upside. Nylon series (POY, FDY, DTY) rose 10-16% year-on-year, tracking caprolactam, but showed no daily movement, suggesting a wait-and-see stance.
The 'Middle Blockage' in Price Transmission and Procurement Adjustments
The list shows gains concentrated at the most upstream (acrylonitrile, PTA), while downstream yarn and fabric products mostly flat or slightly down. This clearly outlines the core contradiction: upstream costs cannot smoothly pass through to end consumers. For weavers and garment makers, this means raw material increases squeeze their own margins rather than raising final prices. Historical patterns suggest that when upstream gains exceed 15% while downstream stalls, intermediate sectors often adjust capacity or destock within one to two months.
For buyers, chasing rallies blindly is unwise now. The short-term spikes in acrylonitrile and PTA may include speculative elements, while the dip in polyester staple fiber hints at bargaining room. It is advisable to procure in small batches on a need basis, avoid concentrated restocking at highs, and monitor crude oil trends, as they ultimately drive acrylonitrile and PTA costs.
Practical Recommendations
For Procurement Teams - Adopt a 'small-batch, high-frequency' strategy for acrylonitrile and PTA to secure near-term needs without hoarding. - Leverage flat or dipping polyester staple fiber prices to negotiate better payment terms or discounts. - Establish a linkage pricing mechanism between raw material costs and finished orders to partially transfer volatility risk downstream.
For Foreign Trade Firms - Include raw material price adjustment clauses in export contracts to protect margins if acrylonitrile or PTA rise further. - Use futures or forward contracts to hedge PTA and polyester filament price volatility. - Prioritize long-term, large orders to dilute cost fluctuations through scale, while closely tracking exchange rate impacts on imported raw materials.
The current divergence in raw material markets is essentially a redistribution of profits along the chain. Upstream players leverage resource advantages, midstream balances costs and demand, and downstream votes with orders. Textile enterprises must look beyond single products and adopt a holistic supply-chain perspective to navigate volatility and protect their bottom lines.
